Giles’ mother, Anna Moser, said her cause of death is still being determined, but that it happened after she was taken to a hospital.

In 2014, Giles was then four-months pregnant and involved in a car crash.

She and two friends were on their way home from a concert late at night when the driver crashed into a guardrail. The two others in the car were fine, but Giles was trapped in her passenger seat and was unresponsive.

Her baby Leighton was born prematurely in January, weighing just 2 pounds.

Doctors gave Giles a 2 percent chance of recovering, her mother told WATE in 2014.

Giles’ family said in a statement that they were deeply saddened by her death, but know she is no longer “in pain or suffering.”

“We are very Blessed to have her son (Leighton Giles) to help her memory live on,” the statement read.

“Sharista’s son Leighton will grow up knowing how much his mother loved him threw (sic) the stories that we all have to tell him about her. Sharista has been such a strong young lady and we all and everyone will miss her everyday. SharistaStrong.”
